suggestion can you offer for enhancing a specific lesson of a Glencoe
mathematics text? Ideas may include using concrete objects to illustrate
concepts, working with cooperative groups, incorporating ongoing
assessment, or any other strategy that you have used successfully
in your classroom.
This activity was written by a teacher using the 1995 edition of
Mathematics: Applications and Connections, Course 2, lesson
7-4, pages 263-265. The lesson is entitled "Adding Integers."
used students holding a positive or negative sign instead of using
counters. Students took turns in front of the room displaying their
signs. Those at their seats wrote the addition sentence shown by
the human counters. Those remaining after zero pairs sat down represented
3/Lesson 2-3: Mary J., Teacher
"You may want to use bingo chips as counters instead of using paper
models. I also use golf tees instead of cups. Both manipulatives
are inexpensive, more durable, easy to store, and take less set

"I reinforce adding integers by having the students play 'Gotcha'.
The game is played just like 'make-a-square' except integers are
written inside each square formed by a grid of dots. When a player
completes a square, he or she scores the integer inside and takes
another turn. The highest total wins."
3/Lesson 3-5: Janet E., Teacher
Slippery Rock, PA
"Students can use masking tape to create a number line on the floor.
Then they walk along it to subtract integers. Starting at zero and
facing the positive integers, they walk forward for positive integers,
backward for negative integers, and do an about-face at the minus

"I ask my students to look for misleading statistics in magazines
and newspapers. They were amazed at how many examples they found."
3/Lesson 4 Study Guide: Dennis N., Teacher
"For a final project, I have my students select their own survey
question. Then they survey 50 people, organize their findings, and
display the results in more than one form. Afterward, we play 'Classroom
3/Lesson 5-3: Clare P., Teacher
"If a computer is available, students can use software like 'The
Geometric Supposer: Triangles' or LOGO for more practice in classifying
triangles. Working in pairs, one student creates a triangle while
the other classifies it and justifies their answer. Then they switch
3/Lesson 5-4: Lois O., Teacher
"You may want students to do an activity similar to the Mini-Lab
on page 184 to discover that the sum of the angles of a quadrilateral
equals 360° If they use a compass to draw an arc at each angle,
tear off each angle above the arc and rearrange the angles so they
can form a circle (360°)."
3/Lesson 6-9: James R., Teacher
"My students find it easier to use the division method for finding
3/Lesson 7-1: James H., Teacher
"I have students apply the mental math strategy of compensation
to adding fractions."
3/Lesson 9-6: Lorraine J., Teacher
"Lay a mirror on the ground between the school and a student so
he or she can see the top of the school in the mirror. Have others
measure the distances from the mirror to the school and to the student,
and from the student's eyes to his or her feet. Have them set up
a proportion to find the school's height."
3/Lesson 13 Study Guide: Jeanne E., Teacher
"I write each of the 'Words to Learn' on an index card and write
each definition on another card. Then students play a game similar
